has anyone experienced this problem. On perhaps 3 diff. occasions when the temp. is high I try to start my xb12r and it will seem like its locked up and struggles to crank then will start but with a loud metal snap/clunk. it reminds me of my old shovelhead which had a worn out starter gear and ring gear, the gear would sometimes walk over the ring gear if it engaged on the compression side of the stroke. it too would then make a nasty clunk when the gears fell in place. I have pulled off the primary cover, inspected the gears. no signs of wear or damage. there is some play at the starter gear (maybe a 1/6 in.) up down, also some runout at the clutch hub ( of course this is with no tension on the primary chain) I pulled out and engaged the gears then placed a screwdriver in between to see if enough lash existed to walk the gears and i dont believe so. Any help or insight appreciated. Donz
hard starting when hot?

I have the same thing but couldn't find the source. Usually happens when the bike is hot, mostly when stopping for gas. [confused]
I found a trick though, I push the start button for 1/2sec, wait 2-3sec, then start her up... then for some weird reason, I don't get the metal clunk sound.

Your symptoms are common.
Most folks are familiar with the effect of cold weather on a battery's performance, but heat also reduces power out put too, especially batteries that are nearing the end of their lifecycle. The long-stroke, single-throw crank, & moderate compression on our XBs are challenging to a battery that's in a weakened state like yours.
The 'clunk' would be consistent with the starter solenoid sluggishly engaging.
I predict you'll be in the market for a new battery soon.

donz: another "old school" trick is to engage 2nd gear and while sitting on seat gently rock the bike forward until you feel the piston closest to TDC compression release its pressure. that move alone eases initial battery and starter system loads and allows the starter to spin up freely as opposed to bumping up against compression when you first engage the starter button.
